MACHINE FOR FINISHING GLASSWARE.

SPECIFICATION forming part of Letters Patent N 0. 601,898, dated April5, 1898. A li ati fil d November 17, 1897. Serial No. 658,826. (Nomodel.)

To all whom it may concern:

Be it known that we, PATRICK J. MCDON- OUGH and THOMAS E. SHELLY,citizens of the United States, residing at Bellaire, in the county ofBelmont and State of Ohio, have invented certain new and usefulImprovements in Machines for Finishing Glassware, of which the followingis a specification.

This invention relates to machines for finishing, shaping, and polishingarticles of glassware after such articles are taken from what is knownas a glory-hole furnace and im mediately after they are pressed andwhile yet hot and pliable. it is dim or blurry and has to be reheated todestroy such blurred appearance. In this reheating process the articlesbecome more or less out of proportion and shape with irregularity insize.

The prime object, therefore, of this invention is to provide new andimproved means for restoring the articlesto their original or intendedsize and shape and produce such articles in a finished uniform conditionwithout skilled labor.

A further object of the invention is to provide a machine of suchspecial and'peculiar construction and arrangement of parts that articlesof various depths or lengths may be treated without changing thedriving-head which carries the article.

A further object of the invention is to provide a split ring to form aguide 'or gage for a buffer or polishing hand-tool and provided with ahandle by which the ring is raised and removed from the machine,carrying the finished article with it.

A-still further object of the invention is to provide a bufier orhandfinishing-tool of novel and peculiar construction adapted to bemanipulated in connection with the split ring to render the articleswhen finished all of uniform or equal size and shape.

Other objects and advantages accruing from this machine and resulting inits essential advances in the art of finishing articles of glasswarewill be revealed in the specification and claims to follow.

In the accompanying drawings, forming part of this application, Figure 1is a perspective view of the machine in operation. Fig. 2 is a centralvertical section of the machine,

After the article is pressed with the shafts and hand-wheel inelevation,

showing an article of glassware in position to be finished. Fig. 3 is asectional view of the sleeve through which the vertical shaft works,showing the adjustable collar arranged in two different positions fromthat of Fig. 2. Fig. 4 is a perspective view of the hand-ring. Fig. 5 isa perspective view of the buffer or hand finishing-tool. Fig. 6 is anenlarged plan view of the driving-head. 1

The same numeral referencesdenote the sameparts throughout the severalfigures of the drawings.

-The support or stand for the mechanism hereinafter to be referred toconsists of a table 1, having legs 2 of any suitable material, size, andshape and of such height as to be convenient to permit an operator to beseated while manipulating the machine.

The table 1 has a central aperture 1, through which a Vertical shaft 3extends without touching the table, said shaft having a conical bottomend journaled in the head of a set-bolt 4, which keeps the shaft fromdownward movement and which is adjustably secured to one wing 5 of anS-shaped hanger 6, the other wing 7 of said hanger being bolted to theunder side of the table.

A transverse shaft Sis j ournaled in depending arms 9' of a bracket 10,secured to the under side of the table. One end. of the shaft Sisprovided with a hand driving-wheel 11 and the other end of said shafthas a gearwheel 12, which meshes with a pinion 13 on the lower portionof the vertical shaft 3, whereby motion is imparted from one shaft tothe other.

The hand-wheel, the transverse shaft, the vertical shaft, and the gearand .pinion con- .stitute the driving mechanism of the machine.

Adjacent the vertical shaft hole or aperture is bolted the flange 14 ofa bearing-sleeve 15, and directly under said hole is a collar 16,

secured to the shaft to prevent the latter from upward movement. Thelength of the sleeve bearing on the shaft keeps the latter in perfectalinement, and the exteriorof said sleeve forms a bearing upon which aflanged collar 17, hereinafter tobe more fully described, is adjusted.

The top end of the shaft 1 has a reduced portion 18, which iscountersunk and screwthreaded, and a shoulder 19, upon which is placed adriving-head 20, having a concaved top face and secured upon saidreduced portion against said shoulder by a set-screw 21, passed throughthe driving-head into the screw-threaded countersink. This head may bereplaced by similar heads of greater or less size to suit the size ofthe tumbler or other article to be worked by simply removing theset-screw 21.

The flanged collar 17 is secured to the sleeve by a set-bolt 22, and hasa lateral flange 23, a rim 24, and a circular groove 25. Said collar iscapable of vertical adjustment on the sleeve 15 in order to shorten orlengthen the space between the driving-head 20 and the hand-ring 26,carried by the said sleeve to accommodate tumblers or other articles ofVarious lengths.

The ring 26, having a suitable handle 26, is split or has an opening 27.and is provided with an outer lateral flange 28, a top rim 29, a bottomtongue 30, and an inner lateral flange 31, having a cavity or groove 32.The tongue 30 fits in the groove 25 of the collar 17, the flange 28rests upon the collar-rim 24, and the flange 31 is seated upon thetopbody of the said collar. The groove 32 forms a bearing for the edgeor rim of the glass or tumbler 33 in removing the glass or tumbler fromthe machine.

The device for leveling and holding the tumbler on the driving-headconsists of a cup disk 34, having a hollow stem 35, provided with aset-bolt 36, which engages a circular notch 37 in a spindle 38, whichadmits of the free revolutions of the disk-stem on the spindle. Thisspindle is secured to or is part of an arm 39, provided with a handle 29and having an angle portion 40 loosely mounted to turn in a hollowstandard 41, which has an angle-base 42, secured to the top of thetable 1. In order to prevent the arm 39 from turning too far away fromthe driving-head or out of convenient reach of the operator, a portionof the top of the standard 41 is cut away, leaving a stop projection 43,which controls the movement of the arm 39. I

The buifer or finishing-tool consists of two conical jaws 44, shaped tofit when closed together a finished glass or tumbler, each jaw having aninner shoulder 45 for the rim 29 of the ring 26, which rim forms a restand gage for the buffer and prevents the jaws from being closed more orfarther upon one glass or tumbler of a set than the others. The jaws areconnected by a handle 46, secured at each end to the'jaws and having athin central bend 47, which produces sufficient spring tension in thehandle to separate the jaws.

The operation of the machine is as follows: The collar 17 having beenadjusted to suit the glass or tumbler to be finished and the cupdiskswung to one side and the split ring having been placed in position, theboy or other operator who has reheated the tumbler, which is stuck tothe head of a punty, holds it directly over the driving-head and by aslight tap on the punty releases the tumbler onto the driving-head. Thefly-wheel. is given a pull by the left hand of the operator, who at thesame time places the buffer down around the tumbler with the right handand before closing the same applies the disk-cup with the left hand tothe bottom of the tumbler and closes the buffer to the gage. When themachine is stopped, the disk is swung to one side and the finishedtumbler is supported in the groove 32 of the ring, the latter then being put over one of the tumbler-supports and withdrawn therefrom by meansof the handring split or opening, leaving the tumbler upon its support.

It will be understood that one pull on the hand or driving wheel isquite enough to give the machine sulficient motion to finish a tumbler,that the tumbler or other article is carried off the machine by thehand-ring, and that the said ring prevents the buffer from being closedtoo far upon the glass or tumbler.

It is obvious that after the pull given the hand or driving wheel bothhands of the operator are free to handle the other parts of the machine,and the time of revolution of said wheel is sufficient to finish theglass or tumbler.

This machine can be propelled by power instead of hand by substitutingabelt-pulley for the fly-wheel. e claim an advantage in a hand-powermachine for the reason that it can be operated in any part of a factory,

because ordinarily no power is used in the pressing department of aglass-factory.

Having thus described our invention, what we claim. as new, and desireto secure by Letters Patent, is

1. The combination in a glass-finishing machine, of a bearing-sleeve, acollar having a circular groove and adjustable on the sleeve, means toadjust the collar, a ring having a tongue to engage said groove, and agage-rim upon the opposite side of the ring from said tongue, as setforth.
